Awesome! I am going to try this now. I do have a question, why do you have your :8000 link in the "location /" ? Is that personal preference? That is basically like going to www.yoursite.com without any sub folder right?
Yeah, the problem is as seafile is accessed from :8000 not :8000/seafile you were always gonna struggle with your planned setup. cmer has a dedicated url just for seafile.
Oh ok that makes sense! CMER what do you have in the "Instance ID" for your seafile docker configuration?
